I recently overheard a discussion on kiseido about the A1 Joseki, which starts by playing the four corner points and then
playing kosumi (cannot remember for sure). This is a very aggressive opening, possibly leading to very high wins (366.5 points) - and of course equally high losses.
Does anybody know details? Was this just a hoax? How does this strategy work in practise?
unkx80: Where does White play? Playing so low on the board, I think this joseki is not good for Black. Most probably it is a hoax. Especially , it does not surround any territory at all.
It all becomes clear once you realise that A1 could also mean April 1.
schmorp?: That would explain the "very high losses" (White plays normally) and "very high wins" (in case White gets totally confused and resigns) ;)
mes?: "Very high wins" happens when black is much stronger than white and playing for money, using these silly opening moves to draw a sucker in for the kill.
Dave: Go is a zero-sum game of course. The explanation above never claims that the A1 joseki leads to very high wins for Black :-)
